2. The method of claim 1 , wherein step d further comprises: establishing, by the computerized telephone services device, a telephone connection between the originating telephone line and a voice mailbox if none of the telephone lines associated with the common number is answered.

3. The method of claim 1 , wherein step j further comprises: disconnecting, by the computerized telephone services device, the second telephone line from the first telephone connection after passing of the first established telephone connection to the third telephone line.

4. The method of claim 1 , wherein step c further comprises: sending, from the computerized telephone services device, a message to the originating telephone line.

5. The method of claim 4 , wherein the message includes a conventional ringing tone, an audio message, a text message, or any combination thereof.

6. The method of claim 1 , wherein step d further comprises: sending, from the computerized telephone services device, an indication to the originating telephone line that one of the two telephone lines is engaged, that both of the two telephone lines are engaged, that the called party is unavailable, or any combination thereof.

7. The method of claim 1 , wherein step e further comprises: repeating, by the computerized telephone services device, the sending and the waiting a predetermined number of times or until the called party satisfies the challenge, whichever occurs first.

8. The method of claim 1 , wherein step e further comprises: determining, by the computerized telephone services device, that the challenge is not satisfied and therefore not establishing the telephone connection between the originating telephone line and the answered telephone line.

9. The method of claim 1 , wherein the challenge includes prompting the called party for one or more of: a personal identification number (PIN), a password, a name, a number, a character, and a code.
